How to make your own homemade onion soup mix so you can always have it in the house and ready to go even if you run out of those trusty little packets!
A lot of people have favourite recipes that use a packet of onion soup mix, but did you know that you can make it yourself? This homemade onion soup mix is a great recipe to know about so you can always have plenty on hand for all of your dips, casseroles, and secret family recipes!
This recipe makes the equivalent of one packet of regular onion soup mix, but I think it’s a good idea to make a big batch of this and keep it on hand in a big jar so you can just scoop and go! I also really like to use this as a base for whenever I’m making homemade soup!
You’ll need:
- Dried onion flakes
- Vegetable bouillon powder (or you can crumble some cubes if that’s what you have in the house)
- Onion powder
- Paprika
- Black pepper
- Celery seed
If you’re trying to reduce your sodium intake, you can use reduced salt bouillon powder instead of regular and you’ll get all the flavour without overdoing the salt!
